Abstract
A device for manipulating a light radiation by reflecting the light radiation multiple times on at least two reflecting surfaces of a monolithic block made of homogenous transparent material comprises a first and second zone on surfaces of the block for injecting the light radiation to be manipulated, and for extracting the light radiation after manipulation. At least one of the reflective surfaces is micro-structured to impart a determined spatial phase transformation.
